Hi,
Probably already reported, but I couldn't find anything so here it goes:
starting with 4.14-rc1 I see the following during boot:
[ 25.199053] percpu: allocation failed, size=16 align=16 atomic=0, alloc from reserved chunk failed [ 25.200195] CPU: 5 PID: 723 Comm: modprobe Tainted: G E 4.14.0-rc2 #103 [ 25.201290] Hardware name: Dell Inc.

A few more failures follow.
A bisect ended up with the merge commit a7cbfd05f427 ("Merge branch 'for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu").
Cheers, -- Luis
